Integrated Dust Extraction (see figure c)
For basic dust collection, use the dust bag 1 provided.
 Check and clean the dust bag each time after using.
 When sawing aluminium, remove the dust bag to avoid
the risk of fire.
– Insert and turn dust bag 1 onto the extraction adapter 35
in such a manner that the pin of the extraction adapter en-
gages in the recess of the dust bag.
During sawing, the dust bag and the extraction adapter may
never come in contact with moving tool components.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, you can also connect the extraction
adapter 35 to a vacuum hose (Ø 35 mm).
– Insert the vacuum hose into the extraction adapter 35.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Cleaning the Extraction Adapter
To ensure optimum extraction, the extraction adapter 35
must be cleaned regularly.
– Pull off extraction adapter 35 from sawdust ejector 36
with a twisting motion.
– Remove workpiece fragments and chippings.
– Mount the extraction adapter onto the sawdust ejector
again with a twisting motion until it engages over the hold-
ing ring of the sawdust ejector.
Changing the Saw Blade (see figures e1
 Before any work on the machine itself, pull the mains
plug.
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
Use only saw blades whose maximum permitted speed is
higher than the no-load speed of the power tool.
Use only saw blades that correspond with the characteristic
data given in these operation instructions and that are tested
and marked in accordance with EN 847-1.
Use only saw blades recommended by the tool manufacturer,
and suitable for sawing the materials to be cut.
Removing the Saw Blade
– Bring the power tool into the working position.
– Loosen the locking screw 37 with the Allen key (6 mm) 30,
until the linkage 38 can hang freely.
– Loosen fastening screw 39 (approx. 2 turns) with the Al-
len key (4 mm) 30.
Do not completely unscrew the screw.
– Loosen the fastening screw 40 (approx. 6 turns) with the
Allen key (4 mm) 30.
Do not completely unscrew the screw.
– Pull cover plate 41 off of fastening screw 40 toward the
front and bottom.
Bosch Power Tools
– Press locking lever 4 and swing back the retracting blade
guard 6.
Hold the retracting blade guard in this position.
– Hang linkage 38 over fastening screw 40 via a bolt hole.
This holds the retracting blade guard in the open position.
– Turn Allen screw 43 with the Allen key (6 mm) 30 and at
the same time press the spindle lock 42 until it engages.
– Hold the spindle lock 42 pressed and unscrew the Allen
screw 43 in clockwise direction (left-hand thread!).
– Remove the clamping flange 44.
– Remove the saw blade 34.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the interior clamping flange
45.
 When mounting the saw blade, pay attention that the
cutting direction of the teeth (arrow direction on the
saw blade) corresponds with the direction of the arrow
on the blade guard!
– Place on the clamping flange 44 and the screw 43.
Press the spindle lock 42 until it engages and tighten the
screw turning in anticlockwise direction.
– Release linkage 38 from fastening screw 40 and guide the
retracting blade guard down again.
– Slide cover plate 41 under fastening screw 40 again.
– Retighten the fastening screws 40 and 39 again.
– Slide the linkage 38 to its original position and retighten
the locking screw 37 with the Allen key (6 mm) 30.
Operation
e4)  Before any work on the machine itself, pull the mains
–
plug.
Transport Safety (see figure A)
The transport safety-lock 26 enables easier handling of the
machine when transporting to various working locations.
Releasing the Machine (Working Position)
– Slightly push down glide arm 23 by handle 3 to release
transport safety-lock 26.
– Pull the transport safety-lock 26 completely outward.
– Slowly guide the glide arm upward.
Securing the Machine (Transport Position)
– Slide glide arm 23 completely to the rear and secure it in
this position (see "Securing the Glide Arm", page 22).
– Guide the glide arm downward until transport safety-lock
26 can be pushed completely inward.
For additional information on transport, see page 27.
Locking the Glide Arm
The glide mechanism of glide arm 23 can be locked with lock
lever 2. Two glide arm positions are possible:
– Glide arm pushed completely to the rear (for chop-cuts)
– Glide arm pulled completely to the front (for a compact
transport position)
